Abstract
Installation for the automatic leaching in the hydrometallurgical production of zinc, comprising a neutral leaching section and an acid leaching section for leaching zinc roasted ore with an acid leaching solution that overflows from an acid leaching section to obtain a slurry that comprises the combination of an open circuit or direct feed constituted by means for detecting the feed of the roasted ore supplied to said neutral leaching section, means for detecting the flow rate of electrolyte supplied to said neutral leaching section, an electronic computer connected to said means for detecting the speed of feeding and said means for detecting the flow rate to make the necessary computation in response to the application of the signals representative of the power supply and the flow rate coming from said detection means, thereby generating a signal of cont role, control means connected to said computer for generating an instruction signal in response to the application of said control signal from the computer, and a flow control valve for regulating the flow rate of the electrolyte in response to the application of said signal of instruction from said control means; and a closed loop or feedback control constituted by a ph meter to continuously detect the ph value of the slurry after being mixed with the electrolyte, said computer, said control means and said flow control valve, whereby the flow rate of the electrolyte mixed with the slurry can be controlled to automatically maintain the ph value of the slurry at a predetermined constant setting value.
